Introduction to RSC ConnectionsROTARY SHOULDER CONNECTIONSROTARY SHOULDER CONNECTIONS

The following pages are intended to enhance a basic understanding of Rotary Shouldered Connections. Noproprietary connections or tools are considered although most of the same principals apply to both.

Below are some common terms related to connections.

Connection Make-Up and SealingROTARY SHOULDER CONNECTIONSROTARY SHOULDER CONNECTIONS

Rotary Shouldered Connection Threads do not seal having an open channel at thread roots and non-pressurethread flanks which runs from the bore to the shoulder. This space accommodates excess thread compound,thread wear, and foreign material.

Rotary Shouldered Connections only seal at their shoulders. The R.S. Connection is a tapered threaded jackscrew that force the shoulders together. Proper make-up torque seals the shoulders, pre-loading compressionof the shoulders to A.P.I. recommended make-up stress levels designed to maintain this seal during drillingoperations. Proper make-up also structurally bonds the two connection members together such that the boxsupports the pin making it equally as resistant to bending as is the box.

Insufficient Make-Up can lead to washouts, pin cracking, galling, make-up down hole and many other types offailures. Under torque is the most common cause of premature connection failures and damages.

It is essential that rig personnel and equipment make-up connections properly. It is also necessary for fieldservice personnel stipulate the proper make-up of their equipment.

Note: Make-Up Torque is torque in Foot-Pounds needed to achieverecommended make-up stress levels in Pounds Per Square Inch as inthe connection types above.

Connections threads have a certain overall slope which is commonly expressed as “ taper per foot” (TPF). This simply means the amount of change in diameter in inches over a foot in length. Most connections in a group have a similar TPF such as Internal Flush ( IF ) connections with a 2” TPF. There are exceptions. All Regular connections have a 3” TPF with only a 6-5/8 Regular connection having a 2” TPF. Some common tapers for connections are listed below.

THREADS PER

Threads Per Inch ( TPI ) is another specification of the various connections. The most common being 4 TPI, 5 TPI, & 3-1/2 TPI.Dividing the one inch by number of threads per inch results in the Lead of the connections threads. I.e. 4 TPI = .250 Lead.

The axial movement factor indicates the longitudinal movement of a ring or plug gage in relation to a diameter change of a connection. Enlarging the thread diameter 0.010” on a 2 TPF connection results in 0.060” increase gage stand-off. Similarresults occur in the field where burrs or defects on connection threads effectively change their diameters.

Connection Factors and CriteriaROTARY SHOULDER CONNECTIONSROTARY SHOULDER CONNECTIONS

Make-Up Torque : The amount of torque or pre-loaded stress required to force and maintain shoulder sealing.Factors are Dimensional, Material Strength, and to a lesser degree - Friction.

Tensile Yield Strength: The amount of pull that can be exerted on a connection. Factors are Dimensional andMaterial Strength.

Torsion Yield Strength: The amount of twist that can be exerted on a connection. Factors are Dimensional andMaterial Strength.

Bending Strength Ratio: The ratio of resistance to bending fatigue of a box versus a pin ( Balanced at 2.5 to 1 )Factors are dimensional so long as both connections are made of same material.

The sizes and types of connections that are used in a Bottom Hole Assembly must take many variables intoconsideration. Tensile Strength, Torsion Strength, and Bending Strength Ratio ( BSR ) as well as the Make-UpTorque required. Connections should meet or exceed acceptable limits of these criteria when used with a drillstring member’s OD and ID.

Note: It is assumed throughout this presentation that Non-Magnetic Material is 100,000 minimum yield strength. Some companiesrecommend 10 % less make-up for Non-Mag than for steel seeking to reduce thread galling. Non-Mag’s higher galling tendency iscaused by an inability to etch the thread surfaces. This results in metal to metal contact as the grease does not stay coated on theNon-Mag surfaces under the high friction of make-up. It is not relative to material yield strength.

Calculation LocationsROTARY SHOULDER CONNECTIONSROTARY SHOULDER CONNECTIONS

Tensile Strength, Torsion Strength, and Make-Up Torque of mated connections are each found by their own setof calculations. In each case, individual calculations are done for both the pin connection & its ID as well as thebox connection & its OD with the smallest result being the final value. Bending Strength Ratio involves twosimilar calculations but with the results being compared to establish the ratio of each members resistance tobending or bending strength ratio.

No value for a connection can be considered as final until the value of its mate is known. The final results arebased on values of the pin & its ID on one tool and box & its OD on another tool that is to be made-up.

The ID of a box does not impact a box’s strength so long as thread roots are not eliminated which would engagepin threads. The OD of a pin does not impact the pin’s values as long as the OD does not reduce the shoulder ofthe pin below its bevel. This can be seen in illustration below.

Notch Effect of Threads & Relief FeaturesROTARY ROTARY SHOULDERSHOULDER CONNECTIONS CONNECTIONS

Threads are in effect notches in a bar. Notches concentrate stressinduced by bending. The sharper the notch, the higher the resultingconcentration of stresses and the more likely fatigue is to begin acrack. This is why thread roots have a radius - to spread stresses.It is also the reason that relief grooves and bore backs increase aconnections resistance to bending fatigue.

Make-Up TorqueROTARY SHOULDER CONNECTIONSROTARY SHOULDER CONNECTIONS

Make-up torque involves two sets of calculations. The pin & its I.D. is the dimensional basis for one calculation .The box & its O.D. is the dimensional basis for the other calculation. Material yield strength of each member isalso factored into the calculations. The lesser results then determine the actual make-up to be used.

There can be confusion in interpreting make-up charts and the exact values to use. This is especially true ofMWD tools where a box connection with a large ID can lead to reading a make-up chart incorrectly. In readingmake-up charts, the connection must first be found. Second, the proper OD row is found based on the box OD.Third, the ID column is found based on the Pin ID.

The make-up chart OD should be the box OD and the chart ID should be the pin ID.

Similar separate calculations are done for both Box and Its OD and Pin and its ID in order to determine theconnections Tensile and Torsion Strength as well as its Bending Strength Ratios.

The Pin Square Area is taken at the point having the smallest “thread root od” which issubjected to tensil loads and is not supported by the box threads LESS the square area of the pin id.

The Box Square Area equals the square area of the box od Less the square area of the box connectionat the point having the largest “thread root id” and which is not supported by the threads of the pin connection ( at pin end ).

The smallest cross sectional area determines the weakest point, thereby determining the Tensil Strength value to be used.

Bending Strength Ratio ( BSR ) page 1 of 2ROTARY SHOULDER CONNECTIONSROTARY SHOULDER CONNECTIONS

The threads of each connection lend support to the other. Thehighest bending stresses occur in thread roots where thissupport ends causing most pins to crack 3/4” to 1” from theshoulder and most boxes to crack at pin end.

BSR values are based upon the ratio of the cross sectional areaof the box at its highest stress point to a similar cross sectionalarea of the pin at its highest stress point.

BSR values commonly relate to drill collars and other stiffmembers of a drill string. BSR values are not calculated for drillpipe as the flexible tubes do not concentrate high bendingstresses in the tool joints.

HIGHEST PIN STRESS AREA HIGHEST BOX

STRESS AREA

Bending Strength Ratio ( BSR ) describes the relative capacity of a pin with a certain ID and a box with a certainOD to resist bending fatigue when mated together. A BSR of 2.50 to 1.00 is generally considered to be balancedunder average drilling conditions with both the box and the pin being equally resistant to bending fatigue. BSRvalues above 2.50 : 1.00 indicate stiffer boxes relative to the pin while values below 2.50 : 1.00 indicate stifferpins. The stiffer member transmits greater bending stresses to the weaker member causing a faster rate ofbending fatigue than would occur in balanced connections.

Few of the most commonly used drill collar combinations of OD, ID, and connection size and type meet the BSRcriteria exactly, therefore BSR ranges are established using general guidelines. The guidelines include:

1. 2.25:1 to 2.75:1 Small drill collars, 6” od or less 2. 2.25:1 to 2.85:1 Small drill collars relative to hole size. ie 8” od in 12-1/4” hole. High RPM, Soft formations 3. 2:25:1 to 3.20:1 Large drill collars relative to hole size. Ie 10” od in a 12-1/4” hole, 8” in 9-7/8” hole

Low RPM, hard or abrasive formations. 4. 2.25:1 to 3.40:1 Condition as in #3 with large collars having low torque and relief features 5. 2.50:1 to 3.00:1 Abrasive formations where loss of OD is severe.
